AB  - BACKGROUND: The repeat power ability (RPA) assessment is used to test the ability 
      to repeatedly produce maximal ballistic efforts with an external load. The 
      underpinning physical qualities influencing RPA are undetermined. This study 
      aimed to gain further insight into the physical qualities that determine RPA by 
      analysing the association between physical qualities and an assessment of RPA. 
      MATERIALS AND METHODS: Ten well-trained male field hockey players performed an 
      RPA assessment consisting of 20 repetitions of loaded countermovement jumps 
      (LCMJ20), with a percent decrement score of peak power output calculated. Over a 
      two-week period, each participant performed the YoYo Intermittent Recovery Test 2 
      (IRT2), a repeated speed ability assessment incorporating a 180 degrees  change of 
      direction (RSA(180)), a 40-meter linear speed test (40 mST), an isometric 
      mid-thigh pull (IMTP), a countermovement jump (CMJ), and a 3-repetition maximum 
      half squat (HS) assessment. Pearson's correlation analysis was used to determine 
      the strength of relationships between each assessment variable and the LCMJ20. 
      The assessment variables with the strongest relationships within each assessment 
      were used in a stepwise multiple linear regression analysis to determine the best 
      predictor model of LCMJ20. RESULTS: RSA(180)percent decrement score (RSA(180)% 
      had a very strong, significant relationship with LCMJ20 (r = 0.736: p < 0.05). HS 
      relative strength (HSrel) was found to have a significant and very strong, 
      negative relationship with LCMJ20 (r =  - 0.728: p < 0.05). Stepwise multiple 
      linear regression analysis showed RSA180 to explain 48.4% of LCMJ20 variance 
      (Adjusted R(2) = 0.484) as the only covariate included in the model. CONCLUSION: 
      The findings indicate that RSA(180) as a repeated high intensity effort (RHIE) 
      task is strongly related to LCMJ20 and is also the best predictor of LCMJ20. This 
      may suggest that RPA can provide practitioners with information on RHIE 
      performance. The variance between assessment methods indicates that RPA may be a 
      distinct physical quality, future research should assess other physical 
      capacities to better understand the factors contributing to RPA.
